I would tend to agree with that, except to add that track sprinting might also be considered an extreme situation in which stiff wheels may give better acceleration. The advantage to low flange hubs, fewer spokes and tangential lacing, in my opinion, is less fatigue on long rides or over rough terrain. The opposite approach, on the other hand, at least "feels" more responsive, and might perhaps actually improve acceleration a bit out of corners on a tight criterium course, although the stronger rider is still going to win, regardless if he rides high flange or low.

While riding I was reflecting on what I wrote earlier. I ralized it was incorrect in that I'm sure there are people who can discern the difference between these variables. What I shouldhave said was that - except for certain extreme situations like very rapid, curving descents - I doubt there is any real difference in speed. Perhaps ther is a difference in _perceived_ speed but that's different than real speed. Of course, I also acknowledge that there are ways in which differences in comfort can have an effect on actual speed. I hope that makes more sense.
